South Korea is considering significant legal changes that could reshape how authorities handle cryptocurrencies during criminal investigations. Tax officials have proposed amendments to the country's Criminal Procedure Act to create a clear legal framework for seizing self-custodied digital assets, addressing what they describe as a major gap in the current law.
The proposal, prepared by researchers from South Korea's National Tax Service, focuses on cryptocurrencies stored in personal wallets controlled by private keys rather than assets held on centralized exchanges.
Why Current Laws Are No Longer Sufficient
Existing regulations generally work well when cryptocurrencies are stored on centralized exchanges, where authorities can request cooperation from the platform to freeze or seize assets.
However, self-custodied wallets present a different challenge.
When users control their own private keys through hardware or software wallets, investigators cannot simply take possession of the assets. Even if authorities obtain a copy of a private key, the owner may still have another copy and move the funds before legal proceedings are completed.
According to the proposal, current legislation was written before blockchain technology became widely adopted and does not provide clear procedures for handling decentralized digital assets.
What Changes Are Being Proposed?
The researchers recommend introducing dedicated legal procedures specifically for self-custodied cryptocurrencies.
Under the proposal, court-issued search and seizure warrants should clearly identify:
- The type of cryptocurrency being seized.
- The amount of digital assets involved.
- The wallet address holding the assets.
- The destination wallet for transferred funds.
- The transfer method.
- Secure custody and storage procedures.
The goal is to establish a transparent legal process that can be consistently applied during criminal investigations.
Jointly Managed Wallets Could Improve Security
One of the most notable recommendations is the creation of jointly managed custody wallets.
Instead of allowing a single investigative agency to control seized cryptocurrencies, the researchers suggest that courts and investigative authorities should jointly oversee custody. This shared-control model is intended to reduce the risk of theft, unauthorized transfers, or misuse of confiscated digital assets.
The proposal also allows temporary transfers to court-designated wallets when immediate movement to a jointly managed wallet is not possible and there is a risk that the assets could be moved by the suspect.
A Growing Focus on Crypto Regulation
The proposal reflects a broader global trend as governments continue updating legal systems to accommodate blockchain technology and digital assets.
As cryptocurrencies become increasingly integrated into financial systems, regulators face the challenge of balancing effective law enforcement with the protection of property rights and technological innovation.
South Korea has been particularly active in developing crypto regulations, and these proposed amendments could become one of the country's most important legal updates for handling self-custodied digital assets.
Looking Ahead
The proposal has not yet become law, but it signals South Korea's intention to modernize its legal framework for cryptocurrency investigations.
If approved, the legislation would establish clearer procedures for seizing digital assets stored in personal wallets while introducing stronger safeguards through court-supervised custody arrangements.
The outcome could also influence other jurisdictions that are exploring how to regulate cryptocurrencies without undermining the principles of decentralized asset ownership.
